The 3M™ Co. 8998 High Temperature Polyimide Tape

3M™ Polyimide Tape 8998 is a dark amber colored polyimide tape with a silicone adhesive meant to withstand heat during high-temperature masking operations. 3M™ Polyimide Tape 8998 features a 2.0 mil thick polyimide backing with a 1.2 mil silicone adhesive.

It is ideal for use in high temperature applications up to 500°F/260°C. Its dark amber color ensures easy identification and alignment. The high dimensional and exceptional tensile strength of this polyimide tape allows it to break through cured paint without silvering or tearing.

Common uses for 3M™ Polyimide Tape 8998 include masking parts for powder coating, masking edges of overlap seams, e-coating, electroplating, anodizing and as a barrier of separation for dissimilar metals. It resists shrinking, curling and edge lifting and removes with zero adhesive residue. The thin, flexible backing seals tight on contact, peels off clean and leaves sharp, clear paint edges.
